Common names may vary in this list but each species has it's correct scientific name.
I have listed below all native Australian plants that are native to or are growing as natives in the Northern Tablelands area. It's possible they are all natives of the Tenterfield area but may have gone extinct in Tenterfield due to removal of native flora and animal grazing. It will take a while to complete and there are no introduced species in this list.
